Hi all, My iMac (2007 model, OSX 10.5.8) is having trouble booting. It loads the white screen with the apple logo and the loading icon underneath for a minute or so, restarts, and repeats this process over and over. Unfortunately I do not have a backup of my files. I've spent two days trying to recover my files, including repair disc and transferring my files from my iMac over to an external HD using a firewire connected to a Macbook Pro. I can access disc utilities using the installation disc and holding 'c' on startup. However, I always get an error when I click repair disc. Using Target Disc Mode, I initially saw my iMac HD on the Macbook. I could not access the files though. When I tried to enter, a message popped up stating I did not have permission to view the HD. Now, the iMac HD won't even mount in Target Disc Mode. Any suggestions on how to recover the data on my iMac? If I cannot find a solution by Saturday, I may just take it to the Apple store. Thanks a lot everyone!
